Refactoring HotmartIE Extractor for Code Convention Compliance

Implemented code convention compliance throughout the HotmartIE extractor. The adjustments span from syntax and structure to proper usage of utility functions. The changes encompass quote usage, inline value extraction, long lines management, import order, fallbacks collapsing, trailing parentheses placement, and the use of conversion and parsing functions like url_or_none and int_or_none for safer data handling.
